sbump?or stump Spyder+Timmy+pump=stump?you tell me what to call it lol

quick tip to anyone making spumps or any type of blowback pump: talk to Azodin tech support and ask about buying an AKP slotted striker. I paid $25 for mine with free shipping. Remember guys, work SMARTER not HARDER.

watch the video it makes thing clearerI don't have the akp striker in on this video
